Nice summary of web 2.0 for the digital humanities

Give users tools to visualise and network their own data. And make it easy.

Harness the self-interest of your users - "help the user with their own research interests as a first priority".

Have an API -"You don’t know what you’ve got until you give it away", "Sharing data in a machine readable and retrievable format, is the most important feature. It lets other people build features for you"

Embrace the chaos of knowledge - "a bottom-up method of knowledge representation can be more powerful and more accurate than traditional top-down methods".
